FAQ: Introduction to JavaScript - Console

Hi,

I wanted to know in whitch cases when you write a code you use signes like this `` and in whitch signs like this " " ?

You could use a different kind of mark like the grave accent ` or single quote ' (apostrophe)
for the string so that you could write [double] quotation marks " inside of that string,

or put a backslash \ in front of the " (like \") inside the string to use " inside the string (it would be an escaped character).

can we only put numbers in the parenthesis of console.log()?..cant we write something like ‘hello world’ in parenthesis?..

we can log a lot of things, numbers, strings, array, objects and more
